4PCS Upgrade Aluminum Mini Vise Clamp Toe Clamp, for Woodworking & Metalworking Milling Project, Size 2.2" x 0.9" x 0.8" (56 x 22 x 21mm), Low Profile

I use these to hold a mdf spoil board over an aluminum main board for parts that need cutting all the way through. These have worked great. The spoil board has never slipped once and the low profile nature of these just makes the a non-factor with spindle motions.

These little things do work. Easily insert in the track of my CNC. Tighten them against the material and they hold tight. Their size makes for a better fit and no worries about hitting a clamp.

Rather pricey,but the item does what it's supposed to do IF you can get it to stay tight item keeps working lose and clamped piece gets damaged

Very nice clamps at a very reasonable price, the only reason I didn’t give a five stars was because one of them came with a missing bolt, but I was able to replace that with an M2 that I had laying around, but still very good for the price.

I have either purchased or fabricated multiple types of clamping solutions for my CNC mill, these toe clamps from Genmitsu are perfect for my use. Low profile so I can use a lower safe Z and I've yet to have one come loose. I read that one reviewer commented that these raised his workpiece when he tightened them, I have not seen that at all as they are actually designed to push your workpiece in and down. I plan on buying more for my 2nd CNC mill. FIVE STARS !!

My husband loves these. He said they hold really well and enable the whole top surface of the stock to be accessible and milled.They use an M6 screw to connect to the T-Slots on his base and they hold very well. The side screw is used to push the jaws into the sides of the stock to keep it in place.The jaws are smooth so the chance of damaging the side of the stock are minimized.

product is ok. horrible customer service

I bought these as an update to the DIY wooden items I'd used for years. These are strong, effective, versatile, and work well. I've now done a half dozen projects on my CNC router with them holding things down and they're working well.
